Introduction The QIAxcel system, when used in conjunction with the QIAxcel RNA Quality Control Kit, provides fully automated quantitative and qualitative analysis of up to 96 samples per run.

The QIAxcel RNA Gel Cartridge provides fast and sensitive analysis of the quality and quantity of total RNA, single-stranded cDNA (fragmented or intact), or cRNA (fragmented or intact). Automated sample loading and analysis reduce manual handling of samples, minimizing the risk of RNA degradation and contamination. The system can detect as little as 5 ng/µl of total RNA and 10 ng/µl of cRNA or single-stranded cDNA.

QIAxcel technology, based on capillary electrophoresis using gel cartridges, provides unmatched resolution, speed, and throughput. QIAxcel Gel Cartridges are reusable, allowing up to 12 x 100 runs to be performed. Preinstalled methods suitable for most applications are provided. Customized methods can also be created — contact QIAGEN Technical Services for more details.

The BioCalculator software supplied with the QIAxcel instrument provides both electropherogram and gel-view profiles of the nucleic acid separation.

QIAxcel DNA High Resolution Kit, QIAxcel DNA Screening Kit, and QIAxcel Large Fragment Kit are also available for use with the QIAxcel system (see “Ordering Information, page 25). These kits allow fast qualitative and quantitative analysis of DNA fragments.

Principle and procedure The QIAxcel system uses capillary gel electrophoresis to enable fast size-based separation of nucleic acids. Unlike traditional agarose gel electrophoresis, the separation is performed in a capillary of a precast gel cartridge. The samples are automatically loaded into an individual capillary and a voltage is applied. The negatively charged nucleic acid molecules migrate through the capillary to the positively charged terminus (Figure 1). As with agarose gel electrophoresis, low-molecular–weight molecules migrate faster than high-molecular–weight molecules. As the molecules migrate though the capillary, they pass a detector which detects and measures the fluorescent signal. A photomultiplier converts the fluorescent signal into electronic data, which are then transferred to the computer workstation for further processing using the BioCalculator software. After processing, the data are displayed as an electropherogram or gel image.


The QIAxcel system offers a number of advantages over traditional slab gel electrophoresis, including:

Higher sensitivity

Less sample wastage (minimal sample input volumes)

Fast analysis of up to 96 samples

Automation

Figure 1. Sample separation process using the QIAxcel system. Nucleic acid molecules are size separated by applying an electrical current to a gel-filled capillary. A detector in the QIAxcel instrument detects the nucleic acid molecules as they migrate towards the positively charged terminus of the capillary. This data are passed through a photomultiplier before being converted to an electropherogram and gel image by the BioCalculator software. (Note: data shown are for DNA; similar data are obtained for RNA.)

Important Notes

Preparing the QIAxcel Gel Cartridge and buffer tray

Important points before starting

The volume of buffer supplied is sufficient for 100 runs of 12 samples. If required, additional buffers can be purchased separately (see “Ordering Information”, page 25).

The 0.2 ml 12-tube strips containing QX Alignment Marker and QX Intensity Calibration Marker (if required) should fit loosely in the MARKER1 and MARKER2 position (see step 13). Tightly fitting tube strips may cause injection problems and damage the cartridge capillary.

QX Alignment Markers should be replaced every 15–20 runs or 3 days, whichever comes first. Additional markers and buffers may need to be purchased (see “Ordering Information”, page 25).

When not in use, the 12-tube strip containing QX Alignment Marker should be stored at –20°C.

Things to do before starting

If preprepared, the 12-tube strip containing QX Alignment Marker should be equilibrated to room temperature (15–25ºC) and centrifuged briefly before use.

If the QIAxcel Gel Cartridge is being used for the first time, intensity calibration should be performed (see step 12 and the QIAxcel User Manual, section 5.4). This step is not necessary if the QIAxcel Gel Cartridge has already been calibrated, unless it is being used on a different QIAxcel instrument or a different computer is used to operate the instrument.


Procedure

Unpacking the QIAxcel Gel Cartridge

1. Remove all buffer bottles from the kit box. 2. Remove the QIAxcel Gel Cartridge from its packaging and carefully

wipe off any soft gel debris from the capillary tips using a soft tissue. 3. Remove the purge cap seal from the back of the QIAxcel Gel

Cartridge and place it in the QX Cartridge Stand. Note: A soft tissue should be used to wipe off any gel that may have leaked from the port.

4. Park the cartridge at the cartridge stand reservoirs containing 10ml wash buffer covered with 2ml mineral oil. Note: Ensure that the capillary tips are submerged in QX Wash Buffer.

5. New cartridges should be allowed to stabilize in the QX Cartridge Stand for 20 minutes prior to use.

Preparing the buffer tray

6. Allow all reagents to equilibrate to room temperature before use. 7. Wash the buffer tray with mild detergent and hot water and rinse

thoroughly with deionized water or water subjected to reverse osmosis.

8. Fill the WP and WI positions of the buffer tray with 8 ml QX Wash Buffer.

9. Fill the BUF position of the buffer tray with 18 ml QX Separation Buffer.

10. Add mineral oil to cover all 3 positions to prevent evaporation. Add 2 ml mineral oil to positions WP and WI, and add 4 ml mineral oil to position BUF.

11. Insert the buffer tray into the buffer tray holder with the slots for the 12-tube strips facing the front of the instrument.

Preparing QX Alignment Marker

12. Load 15 µl QX RNA Alignment Marker into each well of a QX 0.2 ml 12-Tube Strip.

13. Add 1 drop of mineral oil to each well and insert the strip into the MARKER1 position of the buffer tray. Important: The 12-tube strip should fit loosely in the MARKER1 position on the buffer tray.


Installing a QIAxcel Gel Cartridge and smart key

14. Remove the QIAxcel Gel Cartridge from the QX Cartridge Stand. 15. Open the cartridge door and insert the QIAxcel Gel Cartridge into

the QIAxcel system. The cartridge description label should be facing towards the front and the purge hole should be towards the rear of the system.

16. Insert the smart key into the smart key socket. The smart key can be inserted in either direction.

17. Close the cartridge door. The cartridge ID and cartridge type will be displayed automatically in the “Instrument Control” window. Note: The system will not recognize the cartridge and will not operate if the smart key is not inserted.

Intensity calibration

18. Load 15 µl QX Intensity Calibration Marker into each well of a colored QX Colored 0.2 ml 12-Tube Strip and insert it into the MARKER2 position of the buffer tray. Note: If the QIAxcel Gel Cartridge is being used for the first time, intensity calibration should be performed (see the QIAxcel User Manual, section 5.4 for more information). This step is not necessary if the QIAxcel Gel Cartridge has already been calibrated, unless it is being used on a different QIAxcel instrument or a different computer is used to operate the instrument.

Important: The 12-tube strip should fit loosely in the MARKER2 position on the buffer tray.

Sample preparation recommendations The minimum sample volume required for analysis is 10 µl. Less than 0.1 µl of the sample will be loaded onto the QIAxcel Gel Cartridge for analysis.


Typical sample preparation procedure

1. Dilute RNA in nuclease-free water as detailed in Table 1. Table 1. Suggested RNA concentrations

RNA sample type Suggested concentration

Total RNA 0.5–1 µg/µl

cRNA or single-stranded RNA 100–500 ng/µl

Fragmented cRNA or cDNA 250–500 ng/µl

2. Pipet 1 µl total RNA sample (≤1 µg/µl) into a 0.2 ml 12-Tube Strip. 3. Add an equal volume of RNA loading buffer (e.g., Sigma, cat. no.

1386). 4. Heat the solution at 70°C for 2 min on a heating block or PCR

machine. 5. Centrifuge briefly to collect any condensation. 6. Bring the total sample volume to 10 µl using QX RNA Dilution Buffer

and mix the solution by gently pipetting up and down a few times. 7. Analyze the samples immediately.

Note: If less than 12 samples are to be processed, the empty wells should be filled with QX RNA Dilution Buffer or a buffer of similar salt concentration to the sample. Failure to do this may cause damage to the capillaries. For total RNA sample concentration greater than 1µg/µl, cRNA concentration greater than 500ng/µl or fragmented RNA greater than 500ng/µl, it is required to dilute the samples to the concentration suggested in Table 1 before performing denaturation.

Method Selection Preinstalled methods are available for each QIAxcel RNA Gel Cartridge. To select the appropriate method for the samples being analyzed, refer to Appendix C of the QIAxcel User Manual.


Protocol: Determining RNA Quality and Quantity Using the QIAxcel RNA Quality Control Kit with the QIAxcel System

Important points before starting

Before beginning the procedure, read “Important Notes” beginning on page 11.

For optimal results, the solution containing the RNA samples should be approximately pH 7–8.

Determine the optimum QIAxcel method for sample analysis (see Appendix C of the QIAxcel User Manual for more details).

Things to do before starting

Ensure samples have been prepared according to the instructions in “Sample preparation recommendations”, page 13.

Ensure that the QIAxcel Gel Cartridge is set up and all reagents have been prepared according to the instructions in “Preparing the QIAxcel Gel Cartridge and buffer tray”, page 11.

Optional: Create a reference marker table before running samples (see (see Appendix A, page 19 for more details). This can be done after the sample run if preferred.

Procedure

1. Switch on the QIAxcel system at the power switch. 2. Switch on the computer and launch the BioCalculator software. 3. Install the QIAxcel Gel Cartridge.

See the QIAxcel User Manual for more details.

4. Load the buffer tray containing the QX Alignment Marker into the buffer tray holder. See the QIAxcel User Manual for more details.

Note: If being used for the first time, the QIAxcel Gel Cartridge will require calibration (see page 13).

Note: QX Alignment Markers should be replaced every 15–20 runs or 3 days, whichever comes first. QX Alignment Marker should be stored at –20°C between uses.


5. Load the sample strips in position A or a 96-well plate onto the sample tray holder. Note: The cartridge door and sample door of the QIAxcel system must remain closed during operation of the instrument. Opening the cartridge door or sample door during operation will cause the system to stop any action it is currently performing.

18. Click “Run” to start sample processing. At the start of the run, a window containing an electropherogram and a gel image will open (see Appendix A, page 19).


Troubleshooting The QIAxcel User Manual contains a troubleshooting guide, which may be helpful in solving any problems that may arise (see QIAxcel User Manual, Section 8). In addition, extensive user information is also provided in the “Help” menu of the BioCalculator software.

The scientists in QIAGEN Technical Services are always happy to answer any questions you may have about either the information and protocols in this handbook or sample and assay technologies (for contact information, see back cover or visit www.qiagen.com ).


Appendix A: Data Analysis

Aligning the gel image After the run, a gel image window is displayed. This is referred to as the “Folder View”. There is an additional window within the “Folder View” window where data for all channels are visible. Data from each individual channel can be opened by double-clicking on them.

All of the data generated are automatically aligned by the BioCalculator software; however, manual alignment is possible (see procedure below). Alignment compensates for any slight variations between the different capillaries and results in the alignment of the first and last peak (band) across all 12 channels.

the BioCalculator menu bar. The RNA concentration will appear in the results table.

Appendix B: General Remarks on Handling RNA

Handling RNA

Ribonucleases (RNases) are very stable and active enzymes that generally do not require cofactors to function. Since RNases are difficult to inactivate and even minute amounts are sufficient to destroy RNA, do not use any plasticware or glassware without first eliminating possible RNase contamination. Great care should be taken to avoid inadvertently introducing RNases into the RNA sample during or after the purification procedure. In order to create and maintain an RNase-free environment, the following precautions must be taken during pretreatment and use of disposable and nondisposable vessels and solutions while working with RNA.

General handling

Proper microbiological, aseptic technique should always be used when working with RNA. Hands and dust particles may carry bacteria and molds and are the most common sources of RNase contamination. Always wear latex or vinyl gloves while handling reagents and RNA samples to prevent RNase contamination from the surface of the skin or from dusty laboratory equipment. Change gloves frequently and keep tubes closed whenever possible. Keep purified RNA on ice when aliquots are pipetted for downstream applications.

Disposable plasticware

The use of sterile, disposable polypropylene tubes is recommended throughout the procedure. These tubes are generally RNase-free and do not require pretreatment to inactivate RNases.


Nondisposable plasticware

Nondisposable plasticware should be treated before use to ensure that it is RNase-free. Plasticware should be thoroughly rinsed with 0.1 M NaOH, 1 mM EDTA* followed by RNase-free water (see ”Solutions”, page 24). Alternatively, chloroform-resistant plasticware can be rinsed with chloroform* to inactivate RNases.

Glassware

Glassware should be treated before use to ensure that it is RNase-free. Glassware used for RNA work should be cleaned with a detergent,* thoroughly rinsed, and oven baked at 240°C for at least 4 hours (overnight, if more convenient) before use. Autoclaving alone will not fully inactivate many RNases. Alternatively, glassware can be treated with DEPC* (diethyl pyrocarbonate). Fill glassware with 0.1% DEPC (0.1% in water), allow to stand overnight (12 hours) at 37°C, and then autoclave or heat to 100°C for 15 minutes to eliminate residual DEPC.

Solutions

Solutions (water and other solutions) should be treated with 0.1% DEPC. DEPC is a strong, but not absolute, inhibitor of RNases. It is commonly used at a concentration of 0.1% to inactivate RNases on glass or plasticware or to create RNase-free solutions and water. DEPC inactivates RNases by covalent modification. Add 0.1 ml DEPC to 100 ml of the solution to be treated and shake vigorously to bring the DEPC into solution. Let the solution incubate for 12 hours at 37°C. Autoclave for 15 minutes to remove any trace of DEPC. DEPC will react with primary amines and cannot be used directly to treat Tris* buffers. DEPC is highly unstable in the presence of Tris buffers and decomposes rapidly into ethanol and CO2. When preparing Tris buffers, treat water with DEPC first, and then dissolve Tris to make the appropriate buffer. Trace amounts of DEPC will modify purine residues in RNA by carbethoxylation. Carbethoxylated RNA is translated with very low efficiency in cell-free systems. However, its ability to form DNA:RNA or RNA:RNA hybrids is not seriously affected unless a large fraction of the purine residues have been modified. Residual DEPC must always be eliminated from solutions or vessels by autoclaving or heating to 100°C for 15 minutes.

* When working with chemicals, always wear a suitable lab coat, disposable gloves, and

protective goggles. For more information, consult the appropriate material safety data sheets (MSDSs), available from the product supplier.
